Solar and wind are perfectly fine but they aren’t on-demand and cannot fully replace all of our conventional energy needs. What happens when the wind stops blowing or it’s a particular time of year where the sun doesn’t shine as much? You would have to harvest and store that energy in advance to release it to the grid when it’s needed. Our battery tech isn’t where it needs to be to address this problem. You’re ignoring that the alternative to not going nuclear is to continue down the path of fossil fuels like natural gas which contribute to carbon pollution.
